A hexagon
It is an hexagon which has 6 sides
Polygon: A closed shape bounded by straight lines.
A shape with 4 straight lines in which there are 2 parallel and 2 unparallel lines is called a Trapezium.
If the shape has three straight lines and no other lines then it has to be a triangle
A shape made up of line segments is a shape with straight lines, or a polygon. for example, a square has straight lines, or is made up of line segments. A circle is not in that category because it has no straight lines, they are curved.
Two straight lines connected by one curve is the basic horse-shoe shape.
Not really, but if you have many lines it can look like a curved shape.
There is no kind of shape that has a straight line or curved line a kind of element of the following question is "space"...hope this helps
A quadrilateral or quadrangle.
In 2 dimensions, a polygon. In 3 dimensions, a polyhedron.
It could be a stretched circle - a bit like an ellipse except that an ellipse does not have straight lines.
It is a closed 2-dimensional shape bounded by six straight lines.
